Look up King Krule on Wikipedia and you’ll see that he is classified under no fewer than eight genres of music: from hip-hop to indie-rock and even jazz. It’s not the most reliable source of information, but it does give you an insight into how wide-ranging this London lad’s talent truly is.

His debut album, “6 Feet Beneath The Moon,” was released in August — the same week the singer and guitarist (real name: Archy Marshall) turned 19 — to rave reviews. This Wednesday, King Krule plays Webster Hall, and it’s the perfect time to see him skip through his various styles. Prepare to be dazzled.

Ahead of his NYC appearance, here’s a primer on this British wunderkind.

1. He went to the world-famous BRIT School for Performing Arts and Technology, in Croydon, England. In the recent past, the institution has produced musical stars such as Adele, Amy Winehouse and Jessie J — but compared to their polished sounds, Marshall is cut from much rougher cloth.

2. Before enrolling in the BRIT School, Marshall attended two different centers for problem students and was so disruptive that, at one point, he was tested for possible mental illnesses.

3. He’s a man of many guises. Aside from King Krule, he has recorded under the name Zoo Kid, and even now continues to produce music under the names DJ JD Sports and Edgar The Beatmaker.

4. Marshall’s unusually broad sound and style partly stems from being exposed to numerous cultures while growing up in the cultural melting pot of South London. He claims his first girlfriend was Nigerian and she eventually got deported.

5. Frank Ocean and Beyoncé are fans. Queen Bey put his punky, minimalist track “Easy Easy” on her Facebook page during the summer. Most would be thrilled at such an endorsement, but Marshall just shrugged it off, telling MTV, “It doesn’t surprise me. I think my music’s good.” Even more remarkable is the fact that Marshall wrote the song in 2007 — when he was just 12 years old.
